* \brief A value class that defines a 2D point.

* <h3>JavaScript exposability</h3>
*
* A %WPointF is JavaScript exposable. If a %WPointF
* \link isJavaScriptBound() is JavaScript bound\endlink,
* it can be accessed in your custom JavaScript code
* through \link WJavaScriptHandle::jsRef() its handle's jsRef()\endlink.
* A point is represented in JavaScript as an array of two elements, e.g. a point
* WPointF(10,20) will be represented in JavaScript as:
* \code
* [10, 20]
* \endcode
*
* \warning A %WPointF that is JavaScript exposed should be modified only through its \link WJavaScriptHandle handle\endlink.
* Any attempt at modifying it will cause an exception to be thrown.
